What additional information do you need to prove GHI and DEF?

Answer:
HI ≅ EF
Step-by-step explanation:
There are 6 ways to know if 2 triangles are congruent
If any of these groups of corresponding measures are congruent, then the entire triangle is congruent:
SSS
SAS
ASA
AAS
HL
(s - side, a - angle, h - hypotenuse, l - leg)
The drawing shows a congruent side and a congruent angle, so if you had another side to make SAS, you could prove the triangles are congruent
HI ≅ EF makes SAS
